(HealthDay News) — For women undergoing cesarean delivery, suture closure of the skin incision is associated with a reduction in wound complications compared with staple closure, according to a study published in the June issue of Obstetrics & Gynecology.

A. Dhanya Mackeen, MD, MPH, from the Thomas Jefferson University in Philadelphia, and colleagues compared the incidence of wound complications between suture and staple skin closure after cesarean deliver in a prospective randomized trial. Seven hundred forty-six women were randomized to suture (370 women) and staple closure (376 women), after stratification by body mass index and primary vs. repeat cesarean delivery. Wound complications were predefined as a composite of infection, hematoma, seroma, separation of 1cm or more, or readmission for wound complications.

The researchers found that 4.9% of the suture group and 10.6% of the staple group had wound complications (adjusted odds ratio, 0.43). The difference was mainly due to the decreased incidence of wound separation (1.6% in the suture group vs. 7.4% in the staple group; adjusted odds ratio, 0.20).

“Suture closure of the skin incision at cesarean delivery is associated with a 57% decrease in wound complications compared with staple closure,” the authors write.

The study was funded by Ethicon.
